The intelligence of dogs
Dogs can count, understand more than 150 words and intentionally deceive other dogs or people to receive treats, according to a presentation by psychologist Stanley Coren of the University of British Columbia (Canada) at the annual conference of the American Psychological Association.
The researcher, a specialist in canine psychology, has reviewed several studies to conclude that dogs have the ability to solve complex problems and are more like humans and other primates than what was considered.
According to various behavioral measures, the mental abilities of dogs are close to those of a child from 2 years to 2 1/2, he says.
The intelligence of different types of dogs differ and the dog's race determines some of these differences, says Coren. "There are three types of dog intelligence: instinctive (which is determined by race), adaptive (what the dog learns from his environment to solve problems) and obedience and work (the equivalent of the dog). school learning).
Data from 208 judges in the United States and Canada on obedience and work ability show differences by race, Coren reports. Border collies lead, followed by poodles, German shepherds, golden retrievers, Dobermans, Shetland shepherds and finally Labrador Retrievers.
In terms of language, the average dog can learn 165 words, including signals. Dogs in the top 20% for intelligence can learn 250 words. Dogs can also count to 4 or 5.
In games, dogs are able to deliberately try to deceive other dogs or humans for rewards, says Coren. "And they are almost as good at deceiving humans as humans are at deceiving dogs."
The researcher also presented studies exploring the ability to solve problems in the space domain.
